Do I need to re-install my windows 10 if i'll do a hardware change(CPU/MOBO)? My windows 10 is sitting on my ssd.
That is a 100% maybe. Anyone who says "No you don't have to. It always works" is simply blowing smoke.
Sometimes it works with the original OS install
Sometimes it fails badly
Sometimes it works, but you find lingering issues later.
Prepare for a full reinstall. You may not need it, but you'll be glad you prepared for it if you do.
